did so but it turned out that it shows the whole page

)    function show()  
        {  
            $.ajax({  
                cache: false,  
                success: function(html){  
                    $("#content").html(html);  
                }  
            });  
        }  
      
        $(document).ready(function(){  
            show();  
            setInterval('show()',1000);  
        });

Answer 1

setInterval(show,1000);

Answer 2

It updates the whole page because of this command:
You are looking for the "content" container, but you need to find the element of this table. And apparently the entire page is returned to the html variable, but you only need to get the table.
